Coleman DGAA056BDTA Furnace Door Switch
A furnace door switch is a safety feature that blocks the draft inducer and ignitor from turning on in order to prevent injury and fire. It is vital that this part be substituted for a new part as soon as possible especially if you suspect it is not working properly.
What warnings should I watch out for to know if my safety door switch is in need of a replacement?
- The door switch looks worn down
- The system will not even begin to start even when you close the door
